AUTOMOBILE HEATER.

Specification of Letters Patent. Patented B131, 28, 1922.

Application filed November 7, 1919. Serial No. 336,307.

To (all iii/10m, itmay concern:

Be it known that we, WILLARD C. COT- ron'cu-r and fir'rrs F. KIRTLEY, citizens of the llnitcd States, residing at Sharpsville, Ti pton County, Indiana, and Kokom'o,Howard County, Indiana, respectively, have invented certain new and useful Improvements in Automobile Heaters, of which the following is a specification.

This invention relates to heaters primarily for use in connection with automobiles and one feature of the invention is in so constructing the heater that the exhaust from the motor of the automobile may be utilized for heating the interior of the automobile.

A further feature of the invention is in constructing the heater in one piece and making the same seamless, thereby maintaining the cost thereof at a minimum and also preventing leakage of gases from the heater into the body of the automobile.

A further feature of the invention is the provision of means for conducting the exhaust products through the heater in such manner as to cause the exhaust to reach and thoroughly heat all parts of the heater.

Other objects and advantages will be hereinafter more fully set forth and pointed out in the accompanying specification.

In the accompanying drawings which are made a part of this application,

Figure 1 is a perspective view showing one manner of applying the heater to use.

Fig. 2 is a front elevation of the heater.

Fig. 3 is a sectional view therethrough as seen on line 3-3, Fig. 2.

Fig. i is a similar view as seen on line M Fig. 2.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates parts of an automobile body which may be constructed in any preferred manner and 2 indicates the usual form of exhaust pipe such as is commonly used for conveying thev exhaust particles of fuel medium to a convenient discharge point.

In order to utilize the heat of the exhaust products for heating the interior of the automobile, a heater 3 is attached or mounted upon any preferred part of the interior of the automobile and the exhaust products are conveyed to the heater through a pipe 4,

which has one end coupled to the exhaust pipe 2 and the opposite end to the heater 3.

Any suitable form of valve mechanism 5 may be employed for directing the exhaust products through the pipe 4, when turned to one position and cutting the exhaust out from the heater when turned to another position, the valve having a controlling lever 6, which is operable by the driver of the machine.

The heater 3 consists of a hollow body 7, which is formed seamless, consequently no gases can escape from the heater into the interior of the car, the interior of the heater having an integral partition 8, substantially at its transverse center and extending lengthwise of the heater, but terminating short of the ends of the heater to provide passages 9 and 10 at opposite ends of the heater for the passage of the exhaust products from the section of the heater at one side of the partition to the section at the opposite side of the partition.

In order to cause a circulation through the heater and cause the heated product to reach all parts of and thoroughly heat the entire surface of the heater uniformly, the pipe 4; is attached to a hollow neck 11 projecting from the rear face of the body 7 at one side of the partition 8, while an escape port 12 is provided through the rear wall of the body at the opposite side of the partition. a pipe 13 connecting with said port 12 for carrying off the used exhaust-products, the exhaust products, after leaving the neck 11, passing to the ends of the partition and throughthe passages 9 and 10 and thence into the pipe 13, which, like the neck, is placed substantially at the longitudinal center of the heater. This causes the exhaust to pass from the center of the heater to the ends thereof and thence back to the center of the heater before, it can escape, this circulation of the hot gases thoroughly heating all parts of the heater.

As previously stated, the heater may be mounted at any suitable point in the automobile and to more securely hold the heater stationary. extensions 14 are cast with the body. which are provided with openings 15 for the reception of any preferred form of fastening means. The front face of the heater is preferably provided with a plurality of cross ribs 16 which serve to hold garments, lap robes and the like from coming into direct contact with the more intensely heated surface of the heater, thus protecting them against any possibility of injury.

The heater is preferably cast, therefore all the parts thereof are formed integral, consequently there are no seams formed at any point through which the exhaust gases might escape into the car, and furthermore, by forming the heater in this manner, the cost of production is reduced to a minimum while the strength and durability of the device is greatly enhanced.

The invention claimed is:

A heater including a one piece seamless hollow body having openings in one wall and substantially at the longitudinal center thereof for the admission and exit of a'heating tensions projecting inwardly a distance beyond the inner face of said body forspacing the body a distance "from the face of the object to which the heater is secured, said cxtensionshaving openingstherethrough for the reception of anchoring means.

In testimony whereof we hereto aifix our signatures.
